How to Tell If a Website Is Built With Kajabi

Kajabi is a leading all-in-one platform for knowledge commerce — online courses, memberships, coaching and digital products — handling the website, checkout, payments and email in one place. To tell whether a site is built on it, the quickest answer is to open the Network tab and look for assets loading from kajabi-cdn.com, or for a site served on a mykajabi.com subdomain. This guide covers every reliable signal, the all-in-one model behind them, the look-alike course platforms to rule out, and what a Kajabi build tells you about the business and how it monetises its expertise.

What is Kajabi?

Kajabi, founded in 2010, is a hosted platform built specifically for creators and educators who sell knowledge. Rather than assembling a website builder, an LMS, a checkout, an email tool and a funnel builder separately, a Kajabi customer gets all of those in one subscription: a marketing website, online courses and "products", membership sites, a hosted checkout with payments, email marketing and automations, and sales funnels (pipelines). It targets coaches, course creators, consultants, fitness and wellness professionals, and other experts monetising what they know. The pitch is consolidation: instead of stitching together a website builder, a learning-management system, a checkout, an email tool and a funnel builder — and paying for each — the creator runs the whole operation from one place, which is why Kajabi commands a premium price and attracts businesses serious about selling expertise online.

For detection, the key context is that Kajabi is all-in-one and fully hosted, and it is a premium, subscription-priced product. So finding Kajabi is not a bolt-on signal like an embedded checkout — it tells you the entire web presence runs on Kajabi, and that the business is committed enough to knowledge commerce to pay for a dedicated platform. The profile is a creator or small business whose core offering is courses, coaching or memberships. Because Kajabi hosts everything, its infrastructure fingerprints are consistent and hard to hide, even behind a custom domain.

How Kajabi serves sites

A Kajabi site is rendered and served by Kajabi's hosted infrastructure. Theme assets — CSS, JavaScript, fonts and images — load from kajabi-cdn.com (and assets.kajabi-cdn.com), which is the single most reliable signal. Before a creator connects a custom domain, the site lives at a <brand>.mykajabi.com subdomain; once a custom domain is mapped, the address bar shows the brand's domain but the page still pulls assets from kajabi-cdn.com and runs Kajabi's hosted checkout and member-area flows. Kajabi pages also share recognisable theme markup, class-name conventions and structures generated by its page builder.

The commerce and member experiences are Kajabi-hosted too: the checkout, the course player, the membership/login area and the email opt-in forms are all served by Kajabi, with payments typically processed through Stripe or PayPal connected to the Kajabi account. Because everything is hosted, you will not find a separate CMS, LMS or checkout platform — Kajabi is doing all of those jobs. Knowing this — kajabi-cdn.com assets, mykajabi.com domains, Kajabi page markup, and the hosted checkout/member flows — makes detection straightforward.

How to tell if a website uses Kajabi

Confirm at least one strong signal (the asset domain usually suffices).

1. Check the Network tab. Reload and look for assets from kajabi-cdn.com / assets.kajabi-cdn.com. Any such request is a strong, immediate signal.

2. Check the domain. A <brand>.mykajabi.com address conclusively identifies a Kajabi site that has not yet mapped a custom domain.

3. View the page source. Search for kajabi. You will find references to kajabi-cdn.com, Kajabi-specific class names, and sometimes Kajabi script or configuration references.

4. Inspect the checkout and login. A purchase or member-login flow served by Kajabi (Kajabi-styled checkout and course player) confirms the hosted commerce layer.

5. Look at opt-in forms. Kajabi's hosted email opt-in and funnel forms have recognisable markup and submit into Kajabi's system.

What the Kajabi signals look like

GET https://assets.kajabi-cdn.com/themes/…/app.css
GET https://kajabi-cdn.com/…/image.jpg
// Default domain before custom mapping:
https://yourbrand.mykajabi.com/
// Kajabi-hosted checkout and course player served from Kajabi infrastructure

The combination of kajabi-cdn.com assets and (where present) a mykajabi.com domain, plus Kajabi's hosted checkout, is conclusive.

Kajabi versus other course platforms — avoiding false positives

Match the host to keep knowledge-commerce platforms distinct. Kajabi uses kajabi-cdn.com and mykajabi.com; Teachable serves on teachable.com / *.teachable.com and its CDN; Thinkific uses thinkific.com / *.thinkific.com; Podia uses podia.com; Gumroad is a lightweight bolt-on rather than a full site host. Each leaves a distinct domain fingerprint. The main subtlety with Kajabi is the custom domain: a branded address can hide the platform from a casual look, but the kajabi-cdn.com asset requests give it away, so always check where the assets load from rather than trusting the address bar. Because Kajabi is all-in-one, the absence of a separate CMS or LMS is expected and consistent with a Kajabi build.

How reliable is each Kajabi signal?

Assets from kajabi-cdn.com are definitive — the domain is specific to Kajabi and appears even behind custom domains. A mykajabi.com address is equally conclusive. Kajabi's recognisable page markup and class names are strong corroboration. The hosted checkout and course-player flows confirm the commerce layer. The weakest case is a brand-new or heavily customised page where you must look past the custom domain — there, the kajabi-cdn.com asset requests are decisive. As a rule, a single kajabi-cdn.com asset request settles it.

What a Kajabi build reveals about a business

Finding Kajabi signals a knowledge-commerce business — a coach, course creator, consultant, educator, or wellness or fitness professional selling courses, memberships, coaching programmes or digital products. Because Kajabi is premium and all-in-one, its presence indicates a creator or small business that has committed real budget to monetising expertise, not someone dabbling. The site's products and funnels reveal the business model: high-ticket coaching, evergreen courses, recurring memberships, or a mix. If you sell to creators and educators — audience growth, advertising, video tooling, community platforms, or creator-finance services — a Kajabi site marks a serious, monetising knowledge entrepreneur. It also tells you the business runs its email, funnels and payments through Kajabi, which shapes what complementary tools it might still need.

Kajabi in a creator stack

Because Kajabi is all-in-one, its "stack" is largely Kajabi itself: website, courses, checkout, email and funnels in one platform, with payments connected through Stripe or PayPal. Around that, a Kajabi creator typically relies on external traffic and audience channels — social media, YouTube, paid ads, and sometimes a separate newsletter — plus analytics (often Google Analytics or the Meta pixel for ad tracking) layered onto the Kajabi site. For an auditor, the valuable details are whether the site is on mykajabi.com or a custom domain, the products and funnels on offer (which reveal the model and price point), the payment connection, and the advertising pixels present (which indicate paid-acquisition activity); together these characterise the creator's business and growth strategy, with Kajabi as the hub.

A quick Kajabi confirmation walkthrough

Open the site with developer tools on the Network panel and reload. Filter or scan for requests to kajabi-cdn.com or assets.kajabi-cdn.com — any such request confirms Kajabi, even behind a custom domain. Check the address bar and canonical URL for a mykajabi.com subdomain. View the source and search for kajabi to find asset references and class names. Click a buy or member-login button to confirm a Kajabi-hosted checkout or course player. The kajabi-cdn.com asset request alone is your conclusive signal.

A quick Kajabi detection checklist

• Check the Network tab for kajabi-cdn.com / assets.kajabi-cdn.com assets — conclusive on its own.
• Look for a <brand>.mykajabi.com domain.
• Search the source for kajabi references and class names.
• Inspect the checkout and member-login flows for Kajabi's hosted experience.
• Note advertising pixels (Meta, Google) that indicate paid acquisition.
• Don't trust the custom domain — check where assets load from.

Detecting Kajabi at scale

Checking one site is quick, but finding every knowledge-commerce business on Kajabi across a list — to prospect course creators and coaches — calls for automation. StackOptic detects Kajabi (including custom-domain sites) and thousands of other technologies from a real browser. This is especially valuable because Kajabi's custom-domain feature hides the platform from anyone checking only the address bar, so a real-browser scan that reads the asset domains catches Kajabi sites that a naive WHOIS or DNS lookup would miss entirely. Combined with the advertising pixels present, the result is a precise list of monetising course creators who are actively running paid acquisition — among the highest-intent segments in the creator economy.
